On 08/14/2013 halitkaya60 asked, “I have uez GUI 1788-70wvt development kit. I am a student and any experience on this technology. I try to make a GUI application for this kit. Like add video, background picture, music, button and icons. There are many programs to develop the project. CrossWork Studio, Iar Embedded workbench, Keil uvision, Lpcxpresso and code red. I’m so confused which program should be used. And also for GUI desinged how can make easily programmed. Gui builder or other?”

(Follow up post)Answered:
We support IAR EWARM 6.3, KEIL uVision 4.7, and Rowley Crossworks for ARM 2.3. You can pick any one of those 3 for software development. You only need to pick one. IAR EWARM will be the most expensive option most likely. The Crossworks student edition for $150 might be what you are looking for as a student. You will need full 512KB code generation ability. There is a 30 day trial of Crossworks.
Our uEZ 2.05 software is here:
https://sourceforge.net/projects/uez/In the uEZGUI-1788-70WVT project’s Config_Build.h file we have an emWin demo that you can turn on.
You can see here for examples on how to do emWin graphics/GUI.

emWin also has a GUIBuilder but I am not sure how good that is. We mostly/awalys manually write our GUIs in C.

See the quickstart guide in uEZ on how to compile the projects.To create pictures for the uEZGUI slideshow, they need to be targa format images with no “run-length-encoding” that are RGB mode with no transparency layer with “bottom-left origin”. You can use the GIMP software to create these. In some cases icons will need a transparency layer.
For running videos on the unit, you will need to purchase the uEZGUI-EXP-DK to use the high speed 4-bit mode microSD card.
We will be posting a guide soon on how to create videos for uEZ. Note that the uEZGUI-1788-70WVT cannot play videos fullscreen.
These cortex M3s have limitations on what they can do.
Our video player does support audio playback as well. The µEZGUI-EXP-DK has the premium Wolfson I2S audio codec. It will play during video playback.The µEZGUI-EXP-DK also has 4 buttons that you can use. These are accessed through an I2C interface chip.
